Leiomyoma of the lower third of the esophagus is a relatively rare disorder but the most common benign tumor of the esophagus. We present a case of an involuted esophageal leiomyoma, 11 cm in size, treated by the laparoscopic approach. The preoperative computed tomogram visualized a mass 3 × 1.5 cm in diameter in the lower esophagus without an eccentric lumen or compression of nearby organs. Resection of the tumor was indicated according to the patient's symptoms and to exclude malignancy. Laparoscopic enucleation of esophageal leiomyoma was performed. The overall operative time was 205 min. The diagnosis of leiomyoma was established on histopathology and immunohistochemistry staining. The patient resumed the intake of a normal diet on the 5th postoperative day and was discharged from hospital 8 days after the surgery. We have found this minimally invasive operation to be an effective and well-tolerated treatment option, determined by the experience of the surgeon. [ABSTRACT FROM AUTHOR]
